Question

Madge leaves her home at 8:05 to go to school. The drive takes one-third hour each way. If she is at school for 7 hours, what time does she arrive home?

Answer 1

3:45

Explanation:

8.05 + .20 = 8.25

8.25 + 7 = 15.25

Change from military time to standard time.

3.25 + .20 = 3.45

3:45

Answer 2

1/3 of an hour is 60/3 = 20 minutes.

8:05 + 20 minutes = 8:25

8 :25 + 7 hours = 3:25

3:25 + 20 minutes = 3:45

She arrives home at 3:45
